A communication system automatically mutes a microphone in response to a key event detected from a coupled keyboard to prevent delivery of noise generated by the keyboard to a far end of the communication session. A timer is initiated for a time period when the key event occurs, and the microphone remains muted for the time period of the timer. The timer may be restarted to maintain the microphone mute in response to a subsequent key event detected while the timer is running. If the timer expires before a subsequent key event is detected, the microphone can be restored to its previous state (usually un-muted). The system can be applied to a computer coupled to the keyboard and a microphone and having a communication application operating on the computer. Alternatively, the system can be applied to a computer coupled to the keyboard and coupled to an external conferencing unit having a communication application.
